Goo Goo Dolls is a humanoid Stand with a cylindrical head and robotic arms. It has thorn-like structures on its head and upper torso with a set of sharp teeth from its always open mouth.
Its design is based on a mummified monkey.
- Size Reduction: Goo Goo Dolls has the ability to reduce the size of anyone within its range. The victim will shrink to the size of a mouse and the Stand will attack them if Gwess' orders are disobeyed. While the size reduction is instantaneous, people under Goo Goo Dolls' power grow back continuously. It is unknown if this ability is capable of working on multiple targets.
